Solution
The correct option is C Buttercup
The presence of different shaped leaves on the same shoot of a plant depicts heterophylly.
Intrinsic heterohylly is mainly due to changes in the internal features of the plant. The plants cotton, coriander and larkspur exhibit intrinsic plasticity or heterophylly because the leaves of juvenile plants are quite different in shape from those of mature plants.
Buttercup is an example of environmental heterophylly (extrinsic). Compared to terrestrial leaves, underwater leaves have thinner epidermal cell walls. The difference in shapes of leaves produced in air and those produced in water in buttercup represent the heterophyllous development due to the environment.
